The target I designed this around was the Bosch laser target that has dimensions of 18mm x 80mm
Alot of ADAS calibrations when squaring a vehicle to the center line or positioning a target requires measuring from the center of the wheel (IE Honda is 3inches from the center of the wheel assembly). If you do not currently own the Honda tool or the Autel L-Positioning bracket you could also use this.
Note: Bracket is specific for BOSCH target 1608M00806
